F. Problems Requiring Other Resources

F1. We are using pervaporation to separate a benzene–isopropyl alcohol mixture. The pervaporation unit is perfectly mixed. Figure 12-23 in Wankat (1990) shows the separation factor of benzene with respect to isopropyl alcohol vs. the wt. fraction of benzene in the liquid for pervaporation. If operation is at 50°C = Tp = Tout, xin = 0.30 wt frac benzene and the θ = 0.10, find yp, xout, and Tin. (Assume heat capacities and latent heats are independent of temperature.)

Note: Use the lines on the selectivity diagram not the data points.
